KG © FK 6 ASD Copyright by Fey Double laminar sealing rings Lamellenringe for bores Application FK6 ASD Outside clamping double rings (2 rings = 1 set) In contrast to the single wound laminar sealing rings FK 3, FK6 laminar rings are double wound. They are used as grease seals for roller and plain bearings. They are also used as a protection seal in front of hermetically acting seal arrangements. The FK 6 laminar rings must meet special sealing requirements against grease leakage and against dust, dirt and splash water ingress. FK 6 laminar rings provide a uniform radial tension and, in contrast to the FK 3 laminar rings, they have no axial joint gap. The combined ring sets FK6 ASKD (additional sealing of the groove base diameter) optimize the sealing effect due to the increased labyrinth effect. The FK6 ASD or FK6 ASKD assemblies are normally preferred over the FK6 ISD or FK6 ISKD due to their easier ring installation into the grooves of the ring carriers. Depending on the applications or the technical requirements, the ring carriers can be manufactured from steel, cast iron, light alloy or plastics.
